Upon rotation of the stem in the opposite direction, the controlling assembly will be moved in the .opposite direction, thus causing the tapering faces 22 to release the tapering faces 2| and said assembly may then be readily moved in the reverse direction until the passageway I7 alignes with the flowway 6 and a smooth continuous unobstructed passageway will be provided for the flow of fluid through the valve casing.

The end plate 2 has an internally threaded socket 23 and leading inwardly from the inner end of said socket into the casing there is a reduced duct 24. A plug 25 may be screwed into the socket 23. The inner end of this plug is tapered and when the plug is fully screwed home the duct 24 will be closed by it. The plug 25 has an axial inlet passageway 26 whose outer end is internally threaded to receive a grease gun connection and its inner end is overturned so that when the plug is fully screwed home, said inner end will be closed as shown in Figure 1.

The plug 25 may be partly unscrewed and a grease gun connected to it and a lubricant may be forced into the casing i which will flow through the external longitudinal grooves 2'! in the carrier so as to completely fill the interior of the casing on both sides of the valve carrier. This lubricant will flow through the channels l4 so as to lubricate the stem bearing and when the casing is completely filled with the lubricant the grease gun may be detached and the plug 25 screwed fully home to prevent the escape of the lubricant.

The drawing and description are illustrative merely while the broad principle of the invention will be defined by the appended claims.

What we claim is:

1. A valve assembly comprising a valve casing having a passageway for fluid therethrough, a controlling assembly in the casing including a carrier having a passageway therethrough and having a laterally movable valve seated within the carrier, said carrier also having longitudinal bores and being movable to one position to align said passageways and to another position to align the valve with the passageway through the casing, post-like guides anchored to the casing and whose free ends are extended into said bores and provided with tapering faces, said valve having faces which co-act with the tapering faces of the guides to eifect'movement of the valve into sealing relation with the inside wall of the casing around the casing passageway when the valve is moved into alignment therewith.

2. A valve assembly comprising a valve casing having a passageway for fluid therethrough, a controlling assembly in the casing including a carrier having a passageway therethrough and having a laterally movable valve seated in the carrier, said carrier having a longitudinal guideway and being movable to one position to align said passageways and to another position to align the valve with the passageway through the casing, a guide anchored to the casing and Whose free end is extended into said guide-way, said valve having a tapering face which oo-acts with the free end of the guide to effect movement of the valve and carrier into sealing relation with the inside walls of the casing around the casing passageway when the valve is moved into alignment with said casing passageway.

3. A valve assembly comprising a valve casing having a passageway for fluid therethrough, a controlling assembly in the casing including a carrier having a passageway therethrough and having a laterally movable valve seated in the carrier, said carrier also having a longitudinal guide-way and being movable to one position to align said passageways and to another position to align the valve with the passageway through the casing, a post-like guide anchored, at one end, to the casing and whose free end is extended into,

and terminated in, said guide-way, said valve and the extended end of said guide being formed with oo-acting parts effective to move the valve and carrier into sealing relation with the inside walls of the casing around the casing passageway when the valve is moved into alignment with said casing passageway.
